Treatment of heart attack An acute heart attack (myocardial infarction) is a true emergencysince a complete blockage of the blood supply will cause part of the heart muscle to die and be replaced byscartissue. This lessens the ability of the heart to pump blood to meet the body's needs. ...
A damaged wire cannot send a proper electrical signal, making the computer believe a part has failed. #4 – Failing Clutch or Transmission A failing or failed clutch can also cause a vehicle to enter limp mode. Improperly adjusted linkage, and bad solenoids in the transmission will activate li...
That's right: many cars run the water pump off the timing belt, and water pumps start failing at 75,000 miles. Timing belt driven water pumps normally last for the manufacturer's recommended interval for replacing the belt (100,000 miles or so) but if you're replacing the belt you migh...
An exception is made for pregnancy, where an elevated blood pressure of 140/90 needs to be evaluated for the risk of preeclampsia and quickly treated to avoid injury to mother and fetus. For those who have markedly elevated blood pressures and target organs are acutely failing (e.g.,heart a...
The heart is an organ composed primarily of muscle and is responsible for pumping blood to all tissues.
Shock is a culmination of multiple organ systems in the body that have failed or are in the process of failing. Even with the best of care, there is a significant risk of death. The mortality rate for shock depends upon the type and reason for the shock, and the age and underling heal...
Failing to maintain social distancing (at least 6 ft apart) Not performing frequent hand washing/hand sanitizing disease (for example, cirrhosis) , bronchitis, emphysema, idiopathic pulmonary fibrosis, cystic fibrosis, pulmonary) treatment, bone marrow or organ transplant, immune deficiencies, HIVwith ...
a scenario can exist in which the damaged lung tissue acts as a one-way valve allowing air to enter into the pleural space but not allowing it to escape. The pneumothorax size increases with each breath and can prevent blood from returning to the heart and allowing the heart to pump it ...
For those who have markedly elevated blood pressures and target organs are acutely failing (e.g.,heart attacks, aortic dissections,strokes,kidney failure, eye damage), emergent blood pressure control is a priority. In these situations, there often is no cure, but rather the goal is to minimiz...
increase the force of contraction in both normal and failing heart muscle. However, they have a narrow therapeutic range, and dosages are commonly limited by the toxic side effect. Catecholamines exert a positive inotropic effect by activating cardiac β1-receptors, but their usefulness is limited...
